Aaah... A sacrifice of the flesh. Nothing else is quite as effective
at satisfying whatever gremlins are causing mechanical woes...
There's this stuff called duct tape you can wrap around sharp things
like injection pipe clamps... And masking tape for the edges of the
holes in panels (doors) that you might reach through...

OK I replaced the offending glow plug (thank you to the suggester of
the Gearwrench -- made the job much easier), car still did not want
to start. So I CHANGED THE FUSE (do you know the fuse is
permanently charged with 12V, and if they had moved the relay about
a half inch over a screwdriver would go on that inner screw really
really easy, and if you use a little ratchet driver with a philips
bit you wouldn't make big sparks and try to weld it to the car? You
knew that right? Maybe on next year's 126 you can make that minor
change....) and it started up nicely. The old fuse looked fine,
tested fine, but there you go. Maybe a few sparks cleared out the
tubes or something.
That plug was a bugger to get out, more or less, the gearwrench
helped a lot though I dropped it twice -- I have a nice cut on my
left hand from that injector connector bracket that was placed Just
So, to catch the back of your hand when you change the back glow
plug. I guess those German engineers are getting back at us.

Rich, our cars must have been plotting. This a.m. my wagon refused
to
start; no glow timer light. She'd been idling very rough during cold
idle for the first 30 seconds or so over the last month, and so I was
suspicious of the glow plugs. I'd tested resistance a couple weeks
ago
but all seemed OK. Tested again this a.m., all plugs tested fine and
fuse looked good. Still no glow light, no start. Extended
cranking of
the engine wouldn't even get one cylinder to light off. Put the
battery
on the charger and took a closer look at the fuse, and sure enough it
had a hair-line crack.
Check my spare fuses - 30 Amp only - darn!
Used a piece of 14 gauge wire to jumper the fuse screws, and she
started
right up. Will be attempting to purchase two fuses locally after
work
today...
I'm still trying to figure out the rough cold idle; I may have to rig
the in-line ammeter and test the plugs that way.

Subject: [MBZ] One bad glow plug spoils the whole bunch?
The SD has been reluctant to start recently (in the "cold" weather we
have here) so I just checked on it. Looks like the rearmost glowplug
(#5?) is bad, I get open (OL) reading on the ohmmeter while the
others
are in the 0.6ohm range. The glow plug fuse and relay are OK,
getting
12V across the fuse and at the relay pins until the relay clicks
off. None of the glow plugs seem to be warming up though
(according to my
calibrated finger). Can that one bad glow plug cause the others
not to
heat up?
I don't have a amp clamp, but if there is 12V at the plug wires at
the
relay it should be getting juice to all of them?
I'll go out to make sure there is 12V at each plug connector to make
sure the connector didn't go bad or something.
That last plug looks like a bugger to get out too.
